Description

Technical Field

[0001] The present invention belongs to the technical field of lighting devices, and particularly relates to an end cap, a cable installation structure and a lamp. Background Art

[0002] In lamps such as wall washing lights and strip lights, the cable passes through an end cap provided at the end of the lamp housing and enters the lamp body for wiring. In order to facilitate the passing of the cable, the wire passing holes of the end cap are mostly waist-shaped holes or round holes, and the opening size is slightly larger than the outer diameter of the cable.

[0003] The following problems are likely to occur during the production of the cable and the end cap: 1. The cable is mostly produced by an extrusion process, and its accuracy is low. The wire diameter usually varies within the range of ±0.3 mm of the outer diameter of the cable, resulting in a poor matching degree between the wire passing hole and the cable. 2. The wire passing hole is usually a through hole processed by die forming or machining, and it has high requirements for dimensions. Being too large or too small will cause unpredictable production and assembly difficulties during the production process. 3. Due to the dimensional deviations of both the outer diameter of the cable and the wire passing hole, the following situations will occur during the assembly process: (1) The aperture of the wire passing hole is large and the outer diameter of the cable is small. In this case, the cable can pass through easily; however, when pouring glue, because the gap between the cable and the wire passing hole is large, it is easy to have glue leakage. At this time, manual cleaning of the appearance has to be added; or a paste-like substance is filled in the gap between the cable and the wire passing hole before pouring glue to prevent glue leakage. But this increases the processing difficulty, labor cost and production time; (2) The aperture of the wire passing hole is small and the outer diameter of the cable is large. In this case, it will be difficult for the cable to pass through the predetermined wire passing hole, resulting in a longer processing time and increased cost; or it cannot pass through and needs to be reamed, directly increasing the cost. Summary of the Invention

[0057] Embodiment 1

[0058] Reference Figures 1 - 5, this embodiment provides an end cap 100, which is arranged at the end of a wall washer or a strip light. The end cap 100 includes an end cap body 1 and a cable installation channel 2. The cable installation channel 2 is arranged in the end cap body 1. One end of the cable 200 is guided by the cable installation channel 2, passes through the end cap body 1, and then is electrically connected to the lamp body.

[0059] The end cap body 1 includes a first end 11, a second end 12, a base 13 and a top 14. Among them, the first end 11 and the second end 12 are arranged opposite to each other in the longitudinal direction Y. According to the forward direction of the cable 200, the first end 11 is the front end of the end cap body 1, and the second end 12 is the rear end of the end cap body 1. The first end 11 is provided with a first opening 111 for the cable 200 to penetrate. According to the shape matching with the cable 200, the first opening 111 can be provided with an oval hole or a round hole. In some embodiments, the cable 200 is a flat cable, and the shape of the first opening 111 is set to be oval, or elliptical or racetrack-shaped.

[0060] The base 13 and the top 14 are arranged opposite to each other in the height direction Z, and the base 13 is fixedly connected to the bottom of the lamp body end in a fitting manner. In this embodiment, the top 14 has a hollow structure, and the top 14 is provided with a second opening 141 for the cable to pass through.

[0061] The cable installation channel 2 is arranged in the end cap body 1 along the longitudinal direction Y, and the cable installation channel 2 guides the cable 200 to pass through the end cap body. Specifically, the cable installation channel 2 includes an inlet part 21, a supporting and guiding part 22 and an arc guiding part 23. The inlet part 21 is provided with a segmented inner side wall 210 for guiding the cable to pass through the inlet part 21 and enter the supporting and guiding part 22. The supporting and guiding part 22 is arranged on the base 13, and the supporting and guiding part 22 is provided with an inclined surface 221 for guiding and supporting the cable 200. While supporting the cable 200, the inclined surface 221 also guides the cable 200 to the arc guiding part 23. The arc guiding part 23 includes an arc guiding surface 231 and a limiting block 232. Among them, the arc guiding surface 231 guides the cable 200 to the second opening 141 and passes through the second opening 141, and the limiting block 232 feeds back and restricts the forward movement of the cable 200. When the outer shell 203, or the skin or sheath of the cable 200 reaches the limiting block 232, it can no longer move forward smoothly. At this time, information can be fed back to the operator: the cable installation is in place; at the same time, the limiting block 232 also restricts the cable from continuing to move forward.

[0062] During the installation process of passing the cable 200 through the end cap, the cable 200 first enters the cable installation channel 2 from the first opening 111, passes through the inlet part 21, the supporting and guiding part 22 and the arc guiding part 23 in sequence, and then passes through the second opening 141; and, the limiting block 232 feeds back that the installation is in place and restricts the forward movement of the cable 200.

[0063] In some embodiments, the end cap body 1 further includes a pair of side portions 15 oppositely arranged in the transverse direction X, and the side portions 15 are located on both sides of the cable installation channel 2. A support seat 151 is provided on the side portion 15. The support seat 151 surrounds the periphery of the cable installation channel 2, which can improve the structural strength of the cable installation channel 2 in the transverse direction X. A fixing hole 152 may be provided on the support seat 151 for fixedly connecting with the lamp body.

[0064] Along the forward direction of the cable 200, the inlet portion 21 includes a first inlet groove 211, a second inlet groove 212, and a third inlet groove 213. The first inlet groove 211 communicates with the outside through a first opening 111. The second inlet groove 212 is disposed between the first inlet groove 211 and the third inlet groove 213, and the grooving dimensions of the first inlet groove 211, the second inlet groove 212, and the third inlet groove 213 gradually decrease in sequence.

[0065] Specifically, since the inner sidewall 210 of the inlet portion 21 is arranged in a segmented manner, the inner sidewall structures of the first inlet groove 211, the second inlet groove 212, and the third inlet groove 213 are all different, and the grooving dimensions gradually decrease in sequence. The grooving dimension of the first inlet groove 211 is larger than that of the second inlet groove 212, and the grooving dimension of the second inlet groove 212 is larger than that of the third inlet groove 213. The first opening 111 and the first inlet groove 211 present a trumpet-shaped groove structure, which can smoothly guide the wiring end 210 of the cable 200 to penetrate into the first inlet groove 211, and then pass through the second inlet groove 212 and the third inlet groove 213, and exit through the second opening 141. The grooving dimension of the second inlet groove 212 gradually tightens until the third inlet groove 213 is tightly fitted with the outer shell of the cable.

[0066] It should be noted that in this embodiment, the inlet portion 21 is formed by surrounding the first end portion 11, the base portion 13, and the top portion 14, and the inlet portion 21 penetrates through the first end portion 11. In the first end portion 11, a third opening 113 is further provided. The third inlet groove 213 communicates with the supporting and guiding portion 22 through the third opening 113, and the cable is tightly fitted in the third inlet groove 213.

[0067] Combined with reference to Figure 1 and Figure 3 , the cable installation channel 2 has a center line L in the longitudinal direction Y. In the cross-section along the center line L, the first inlet groove 211 and the first opening 111 are respectively connected at A1 and A2, the first inlet groove 211 and the second inlet groove 212 are respectively connected at B1 and B2, the second inlet groove 212 and the third inlet groove 213 are respectively connected at C1 and C2, and the third inlet groove 213 and the third opening 113 are respectively connected at D1 and D2.

[0068] Among them, there is a relational expression: H A1A2 >H B1B2 >HC1C2 = H D1D2 .

[0069] H A1A2 is the distance between A1 and A2 in the height direction;

[0070] H B1B2 is the distance between B and B in the height direction;

[0071] H C1C2 is the distance between C and C in the height direction;

[0072] H D1D2 is the distance between D and D in the height direction.

[0073] Specifically, the first wire inlet groove 213 and the first opening 111 present a groove structure with a flared opening, which can guide the cable 200 into the first wire inlet groove 211. The slotting size of the first wire inlet groove 211 gradually decreases, presenting as H A1A2 > H B1B2 . In the first wire inlet groove 211, its inner sidewall can be a planar structure or a curved surface structure that is recessed towards the base 13 or the top 14 respectively.

[0074] The cable 200 enters the second wire inlet groove 212 through the first wire inlet groove 211. The slotting size of the second wire inlet groove 212 also gradually decreases, presenting as H B1B2 > H C1C2 . As Figure 3 shown, the reduction amplitude of the slotting size of the second wire inlet groove 212 is smaller than that of the first wire inlet groove 211. Similar to the first wire inlet groove 211, the inner sidewall of the second wire inlet groove 212 can be a planar structure or a curved surface structure that is recessed towards the base 13 or the top 14 respectively.

[0075] Then, the cable 200 enters the third wire inlet groove 213 through the second wire inlet groove 212. The slotting size of the third wire inlet groove 213 remains unchanged. The inner sidewall of the base of the third wire inlet groove 213 is parallel to the inner sidewall of the top, presenting as H C1C2 = H D1D2 . Since the outer shell 203 of the cable 200 has flexibility, after the cable 200 enters the third wire inlet groove 213, the inner sidewall of the base and the inner sidewall of the top respectively squeeze the outer shell of the cable, forming a tight fit state. On the one hand, it can limit the movement of the cable 200 in the height direction Z; on the other hand, it can avoid the occurrence of glue leakage in the subsequent resin (glue) pouring process and reduce the cleaning process.

[0076] If only the first wire inlet groove 211 and / or the second wire inlet groove 212 are adopted, the interference amount between the wire and the wire inlet part is insufficient, and the wire cannot form a tight fit state with the wire inlet part, easily resulting in glue leakage; if only the third wire inlet groove 213 is adopted as the wire inlet part, the slotting (hole opening) size of the third wire inlet groove will be too large, and the wire still cannot form a tight fit state, and glue leakage will still occur. If the slotting (hole opening) size of the third wire inlet groove is made smaller, it will be difficult or impossible for the wire to penetrate.

[0077] In this embodiment, the wire inlet part 21 composed of the first wire inlet groove 211, the second wire inlet groove 212 and the third wire inlet groove 213 is adopted. After smoothly guiding the wire to pass through, the problem of difficult wire threading is solved; the third wire inlet groove 213 forms a tight fit state with the wire, which can limit the wire and avoid glue leakage at the same time, and solves the problem of glue leakage caused by the mismatch between the size and the wire.

[0078] Combined with reference Figure 3 and Figure 4 , the base 13 has a base surface 130. Both the line segment C1D1 and the line segment C2D2 are parallel to the base surface 130, that is, the inner side walls of the third wire inlet groove 213 located at the base 13 and the top 14 are parallel to the base surface 130. In the cross-section, the third wire inlet groove 213 is rectangular, its height remains unchanged, and the inner side walls of the base and the top are plane structures.

[0079] In the cross-section, both the first wire inlet groove 211 and the second wire inlet groove 213 are isosceles trapezoid structures with the center line L as the axis of symmetry.

[0080] Taking the inner side wall of the top as an example for illustration, the line segment A1B1 forms an angle α with the base surface 130, and the line segment B1C1 forms an angle β with the base surface 130; the angles α and β have the relationship: α > β. The reduction amplitude of the slotting size of the first wire inlet groove 211 is greater than that of the second wire inlet groove 212.

[0081] After the wire first enters the first wire inlet groove 211, as the wiring end of the wire advances, the outer shell gradually passes through the second wire inlet groove 212 and is then clamped by the third wire inlet groove 213 to achieve a tight fit state.

[0082] Furthermore, the support and guide part 22 is also provided with a receiving groove 222, which is recessed towards the base surface 130 and is used to receive the resin glue flowing into the support and guide part 22. Moreover, the bottom of the receiving groove 222 is lower than the plane where the line segment C2D2 is located. After the resin glue flows into the support and guide part 22, it will not flow back into the wire inlet part 21 after being poured.

[0083] In the arc-shaped guiding portion 23, the limiting block 232 is centrally arranged on the arc-shaped guiding surface 231, and the limiting block 232 is in contact with the inclined surface 221 of the supporting guiding portion 22. In the end cover 100 of this embodiment, the limiting block 232 is a stop step structure. By arranging the limiting block 232 in the forward direction of the cable, the operator can clearly define the penetration length of the cable and the forward position of the outer shell (skin), avoiding the situation that the cable is not fully penetrated, resulting in a gap between the cable and the third cable inlet groove of the cable inlet portion, and thus poor waterproof effect.

[0084] The limiting block 232 can standardize the penetration length of the cable and avoid the situation that the cable is not installed in place. The setting of the limiting block 232 can ensure the consistency of the cable outlet length of each end cover, which is particularly important when there is no space to place the excess wire in a narrow space.

[0085] The arc-shaped guiding surface 231 is a ramp structure with a curved surface. On the one hand, it can guide the wiring end of the cable to quickly pass through the second opening; on the other hand, the arc-shaped guiding surface 231 can also guide the resin glue to fill into the accommodating groove 222 through the inclined surface 221. The cable is in a partially suspended state above the accommodating groove 222 of the supporting guiding portion. During glue filling, the resin glue can enter the bottom of the cable, thereby wrapping the cable and making the installation stable and reliable.

[0086] The end cover provided in this embodiment has the slotting dimensions of the first cable inlet groove, the second cable inlet groove, and the third cable inlet groove of the cable inlet portion decreasing in sequence to guide the cable into the supporting guiding portion; and, the cable is tightly and matingly connected with the third cable inlet groove to achieve a highly matching state, solving the problems of difficult cable penetration through the end cover and glue leakage; the limiting block on the arc-shaped guiding surface can longitudinally limit the forward movement of the cable, standardize the penetration length of the cable, enable the operator to clearly penetrate the cable into the specified position, and avoid the situation that the cable is not installed in place; in the horizontal and height directions, the third limiting groove limits the cable to prevent water ingress and glue leakage.

[0087] Embodiment 2

[0088] On the basis of Figures 1 - 5 refer to Figures 6 - 8, this embodiment provides a cable installation structure, including a cable 200 and the end cap 100 of Embodiment 1. The cable 200 includes a conductor 201, an insulator 202, and a sheath 203. The insulator 202 is coated on the outer periphery of the conductor 201, and the insulator 202 can also be called a core wire; the sheath 203 is coated on the outer periphery of the insulator 202, and the sheath 203 is made of an insulating material. The sheath 203 can also be called an outer skin or a jacket. Among them, one end of the cable 200 is a terminal end 210, which is used to pass through the end cap 100 and be electrically connected to the lamp body; the other end is connected to a waterproof connector 300. The cable 200 of this embodiment is a flat cable. After the terminal end 210 of the cable 200 strips off part of the sheath 203 and the insulator 202, the cable installation channel 2 guides the terminal end 210 to pass through the end cap body 1. The sheath 203 abuts against the limiting block 232 and is restricted from moving forward longitudinally, and the sheath 203 is tightly connected to the cable inlet portion 21. The resin glue 400 passes through the arc-shaped guiding surface 231, and part of the insulator 202 and the sheath 203 are poured and encapsulated in the supporting guiding portion 22 and the arc-shaped guiding portion 23.

[0089] The specific process of the cable 200 passing through the end cap 100 and being installed is as follows:

[0090] S1. After the terminal end 210 of the cable 200 strips off part of the sheath 203 and the insulator 202, the terminal end 210 exposes the rigid conductor 201. The terminal end 210 enters the cable installation channel 2 from the first opening 111, passes through the cable inlet portion 21, the supporting guiding portion 22, and the arc-shaped guiding portion 23 in sequence, and reaches the arc-shaped guiding surface 231. At this time, the upwardly inclined inclined surface 221 lifts the insulator 202 and makes it in a suspended state. The sheath 203 is about to enter the first cable slot 211 from the first opening 111.

[0091] S2. The conductor 201 of the terminal end 210 is guided by the arc-shaped guiding surface 231 and passes through the second opening 141; since the arc-shaped guiding surface 231 has a circular arc surface, when the insulator contacts the arc-shaped guiding surface, the conductor and the insulator are guided and naturally bent to be led out upward from the second opening. Such a guiding method can prevent the insulator and the conductor from moving downward and causing the cable to be unable to move forward continuously. At this time, the sheath 203 enters the second cable slot 212 through the first cable slot 211, and the end of the sheath 203 is about to enter the third cable slot 213.

[0092] S3. When the end of the sheath 203 passes through the third cable slot 213 and reaches the limiting block 232 with a stop step, the sheath 203 abuts against the limiting block 232 and is restricted from moving forward longitudinally, and the two form an interference state. The cable 200 can no longer move forward smoothly. At this time, information is fed back to the operator: the cable installation is in place; at the same time, the limiting block 232 also restricts the cable from moving forward continuously. Moreover, the outer sheath of the cable is tightly connected to the third cable slot to achieve a highly matching state.

[0093] In order to achieve a waterproof sealing effect of the cable in the end cap, potting resin glue 400 is also required. The highly fluid resin glue 400 is guided by the arc-shaped guiding surface 231 and fills into the receiving groove 222 through the inclined surface 221. The cable is in a partially suspended state above the receiving groove 222 of the supporting and guiding portion. During potting, the resin glue 400 can enter the bottom of the cable, and then wrap the cable. Part of the insulator 202 and the housing 203 are potted and encapsulated in the supporting and guiding portion 22 and the arc-shaped guiding portion 23 to form a waterproof sealing layer, making the installation stable and reliable.

[0094] Embodiment 3

[0095] This embodiment provides a lamp, which includes a lamp body and a cable installation structure. The end cap is fixedly connected to the end of the lamp body, and the cable is electrically connected to the power supply component.

[0096] In this lamp, through the mutual cooperation of the supporting and guiding portion and the arc-shaped guiding portion of the end cap, after the cable penetrates longitudinally, it passes out through the second opening opened at the top; the supporting and guiding portion is provided with a receiving groove. While holding up the cable, there is a gap between the cable and the receiving groove. During potting, the resin glue can enter the bottom of the cable and effectively wrap the cable, ensuring the stable and reliable installation of the cable.
